However, the currently existing models are based on rather local data, and thus there is a lack of predictive tools to monitor SC. Aims Our aim was to assess the influence of cover crops on soil chemical properties by considering their different behaviours (biomass production and root density). Methods We characterised soil chemical properties, and plant biomass production during 6 years in field conditions at a tropical soil. Key results Our findings suggest that: (1) green manure practice improved Ca2+, K+, and soil organic carbon (SOC) stock, but none of the studied cover crops were able to improve soil P content; and (2) we found three groups of green manure by considering the SC reduction, namely G1 (low SC reduction) that comprises Crotalaria ochroleuca and Neonotonia wightii, G2 (medium SC reduction) that comprises Brachiaria decumbens, Pennisetum glaucum, and Crotalaria juncea, and G3 (high SC reduction) that comprises Mucuna pruriens, Canavalia ensiformis, Crotalaria spectabilis, Dolichos lablab, and Stizolobium aterrimum. Conclusion We concluded that after 3 years during which soil parameters and the production of most, but not all, cover crops have increased, the deficiency in P did not allow plants to grow well anymore.

The formation of lower-solubility ammonium salts may be a simple and cost-effective way to slow the release of nitrogen (N) from fertiliser sources. Several modified mono-ammonium phosphate (MAP) fertiliser compounds were prepared by adding magnesium silicate to regular MAP fertiliser and reconstituting the granules. This process results in the formation of schertelite that may potentially slow the release of both N and phosphate to soil solution. These modified MAP fertiliser compounds include more citrate-soluble N and phosphorus (P) than standard MAP fertiliser. The fertiliser compounds were added to a P-responsive soil and barley plants were grown for 5 weeks to investigate shoot yield responses to nutrient availability of the modified MAP fertiliser compounds. Reverse dilution tracing techniques were also used to compare the fertiliser solubility and P availability of the modified MAP fertiliser compounds with regular MAP fertiliser. Barley (Hordeum vulgare) plants recovered P equally and efficiently over 5 weeks of growth in the P-responsive soil, suggesting that the fertiliser compounds were sufficiently soluble to meet plant requirements and that phosphate release was not slowed by the formation of schertelite. However, shoot yields were generally lower when the barley plants were grown with the modified MAP fertiliser compounds compared to standard MAP fertiliser. This reduced growth was likely due to decreased N availability through a slower release of N, thus further research is warranted to determine the potential for these products to improve N use efficiency.","PeriodicalId":21818,"journal":{"name":"Soil Research","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141926697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
